How to pass parameters in headers - node.js

Question

I need to call an API from my Angular Node application.For that i have to pass username and password along with header request.How to pass parameters?
I tried below code
From Angular service,
checkUserApi(url: string): Observable<any> {
const headers = new HttpHeaders()
.set('Authorization', 'my-auth-token')
.set('Content-Type', 'application/json')
.set('userName','prismtest')
.set('password','12345678');
return this.http.post('/upload/checkUserApi/', { headers })
.map((response: Response) => {
console.log(response);
return response;
})
}
In Node,
router.post('/checkUserApi',function(req,res,next){
var proxyUrl = 'http://cors-anywhere.herokuapp.com/';
Request.post({
"headers": { "userName": "prismtest","password":"12345678" },
"url": proxyUrl+"https://example.com",
"body": {}
}, (error, response, body) => {
if(error) {
return console.log(error);
}
res.send(response);
});
});

Answer 1

You can pass the form parameters as the second attribute to post request:
checkUserApi(url: string): Observable<any> {
const headers = new HttpHeaders()
.set('Authorization', 'my-auth-token')
.set('Content-Type', 'application/json');
return this.http.post('/upload/checkUserApi/', {username: 'prismtest', password: '123'}, { headers })
.map((response: Response) => {
console.log(response);
return response;
})
}

Can you try below code following
/* SERVICE ANGULAR*/
import {Injectable} from '#angular/core';
import {HttpClient, HttpHeaders} from '#angular/common/http';
import {Observable,of} from 'rxjs';
import { map,catchError } from 'rxjs/operators';
import {User} from '../_models';
const httpOptions = {
headers:new HttpHeaders({'Content-Type':'application/json'})
};
const API_URL = "http://localhost/app/api";
#Injectable({
providedIn:'root',
})
export class UserService{
constructor(private http:HttpClient){}
/**
* POST LOGIN USER
*/
login(user: any) {
return this.http.post<any>(API_URL+"/login", user,httpOptions)
.pipe(map(user => {
return user;
}));
}
}
/*NODEJS*/
/* 1) install $ npm install body-parser --save*/
var bodyParser = require('body-parser');
app.use(bodyParser.json()); // support json encoded bodies
app.use(bodyParser.urlencoded({ extended: true })); // support encoded bodies */
/ POST http://localhost:8080/api/users
// parameters sent with
app.post('/api/login', function(req, res) {
var user_id = req.body.id;
var token = req.body.token;
var geo = req.body.geo;
res.send(user_id + ' ' + token + ' ' + geo);
});

const headerOptions = {
headers : new HttpHeaders({
'Constent-Type' : 'application/json',
'Authorization : 'you token here'
})
}
http.post('you action', {body Params}, headerOptions, function(res){
console.log('your respose is ', res);
})
